[ANN] Blosc 1.1.3 released
Francesc Alted
Announcing Blosc 1.1.3
A blocking, shuffling and lossless compression library
===============================================================
What is new?
============
Much improved compression ratio when using large blocks (> 64 KB) and
high compression levels (> 6) under some circumstances (special data
distribution).
For more info, please see the RELEASE_NOTES.txt file.
What is it?
===========
Blosc (http://blosc.pytables.org) is a high performance compressor
optimized for binary data. It has been designed to transmit data to
the processor cache faster than the traditional, non-compressed,
direct memory fetch approach via a memcpy() OS call.
Blosc is the first compressor (that I'm aware of) that is meant not
only to reduce the size of large datasets on-disk or in-memory, but
also to accelerate object manipulations that are memory-bound.
It also contains a filter for HDF5 (http://www.hdfgroup.org/HDF5) so
that you can easily implement support for Blosc in your favourite HDF5
tool.
